A bifunctional molecular catalyst built up of l-proline grafted polyoxometalate for one-pot three-component green synthesis of heterocycles

Abstract

Both polyoxometalates(POMs) and organic small molecular catalyts have excellent performance in chemical synthesis. The incorporation of nanoscale POMs and organocatalysts allows the full expression of their respective merits and enables...

2,5-Thiophenedicarboxylic Acid Bridging Hexameric CeIII-Substituted Selenotungstate and Its Application for Detecting Mucin 1

“…With the development of science and technology and functional materials, there have been increasing numbers of interdisciplinary articles reported in recent decades. The applications of POMs not only are any longer focused on catalytic, magnetic, and luminescence but also have been extended toward the explorations of enzyme-like activity, electrochemical sensing, etc. − Although POMs with remarkable redox activity have been proven to be potential electrode materials, their application in electrochemical sensors is greatly restricted owing to the shortcomings of poor conductivity. Therefore, some multifunctional composite materials, which combined POMs with metal nanoparticles (NPs), metal–organic frameworks, covalent–organic frameworks, carbonaceous materials, and conducting polymers, were fabricated to take advantage of synergistic effects to improve conductive properties. − The results indicate that the electrochemical sensors of carbon–POM nanomaterials can exhibit a low detection limit, high selectivity, and good antijamming capability.…”

Synthetic methodology of pyrimido[4,5‐b]quinoline derivatives

“…A bifunctional nanomolecular catalyst L-Pro-Mn by grafting L-proline onto an Mn-Anderson-type POM (Polyoxometalate). It has been shown that L-Pro-Mn-Anderson can realize the one-pot alcohol oxidation/ three-component reaction between aldehydes, arylamines, and barbituric acid 147a to synthesize 5-aryl-pyrimido [4,5-b]quinolinediones 178a-k (Scheme 54) [76].…”

Polyoxometalate templated silver-bisphosphine sandwich: structurally tunable hybrid materials

“…Advanced POM-based functional materials are a complicated and challenging research area. 1–7 The utilisation of organic ligands or complex units to functionalize POMs is a unique method for generating organic–inorganic hybrid materials based on POMs. 8–14 These organically functionalized hybrid POMs have been synthesized by replacing one or more oxo or [MoO x ] n + groups with organic functional groups.…”
